This is from urban dictionary:
1. cold lampin' 127 up, 32 down
Tapping into the electrical wires of a street light to power DJ and MC equipment, and sound system, for the use of underground hip-hop performances and battles.
This term was popularized by the Flavor Flav / Public Enemy song of the same name, but since the term is not defined in the song, many assume the phrase to have other meanings.
"Aiyyo, power from the street light made the place dark!
I know a few understand what I’m talkin’ about"
- Mos Def (refering to the practice of cold lampin')
